The Home Studios consist of two rooms:
1) A Control room that contains the majority of studio equipment, computer for recording, monitoring speaker and studio monitors.
2) A tracking room that also contains a number of instruments, amplifiers and speakers used in the tracking process.
The control room is constructed of naked bricks which have been scrubbed of paint to give a rustic appearance and also reduce reverb etc. from the more reflective painted surface. The ceiling is constructed of solid pine lining with layers of insulation above. The floor is constructed of concrete covered in carpet tiles. The surfaces in the monitoring room are quite good in terms of reflections etc. but I am in the process of constructing some portable Acoustic baffles that can be relocated to reduce any unwanted reverberations. The monitoring room can also double as a tracking room for instruments such as acoustic guitar where you are seeking a more lively sound.
In order to reduce the effect of reverb when mastering within the control room I have decided to build a number of portable baffles that can be seated behind the listener to absorb reflections which is otherwise difficult because of the equipment in the room and the small size of the room. The use of nearfield monitors and sitting in the sweetspot will also help to eliminate the negative impact of unwanted reverberations.
The main tracking room is 4.8*2.4 metres in dimension and constructed from a a number of layers from inside to outside as follows:
My original plan was to use the white foam sheets as the studio walls as I believed the surface would reduce echoes and provide a good level of sound isolation because of the thickness of the sheeting. I constructed stud walls to mount the sheets onto.
I have since found out that the sheeting does not reduce external noise as much as I would like and that the sheets which are covered with render when used in the building industry do not provide a tight seal against external noises and breezes.
To further improve noise isolation I have filled the stud wall with insulation batts and covered the external surfaces with ply. This provides the benefit of warmth coupled with the ability to further reduce noise isolation by adding thicker sheets.
At this stage noise isolation is quite good although I am not happy with noise isolation from the roof above and am in the process of installing thicker plywood sheeting between the external roof and the false ceiling of the studio.
The studio ceilings and walls are covered with acoustic eggshell foam to control reverb with the exception of two small walls which have been left as timber panelling and brick to provide a corner with some reverb when required. Portable baffles will be used to isolate these walls as required.
The floor is concreted covered in carpet tiles and rugs that can be rolled back to liven the sound of the room if required.
